[고안의 상세한 설명][Detailed Description of Design]

본 고안은 자동차용 에어백 모듈의 커버에 관한 것으로서 더욱 상세하게는 에어백작동시 쿠션의 팽창이 용이하도록하는 절개부(TEAR SEAM)의 구조를 개선한 것이다.The present invention relates to a cover of an airbag module for an automobile, and more particularly, to improve the structure of the incision (TEAR SEAM) to facilitate the expansion of the cushion during operation of the airbag.

자동차의 에어백은자동차충돌시 운전자와 스티어링휠의 부딪힘과 조수석의 승차자와 대시보드판넬상간의 부딪힘을 방지하여 부상을 최소화하도록 하는 장치이다.The airbag of the vehicle is a device that minimizes injuries by preventing a collision between a driver and a steering wheel and a collision between a passenger seat passenger and a dashboard panel during a vehicle crash.

이러한 에어백은 3점식안전밸트를 장착하였을 경우를 감안하여 소형이면서 안면보호를 목적으로 설치하는 SRS에어백과 안전벨트를 장착하고 있지 않은 상태를 감안하여 설치하는 대형 에어백등으로 구분이 된다.These airbags are classified into SRS airbags installed for the purpose of face protection and large airbags installed in consideration of the absence of seat belts in consideration of the case where a three-point safety belt is installed.

이러한 에어백은 충돌시 이를 센서에 의하여 전기적인 신호로 감지되고 인플레이트(INFLATER; 에어백시스템의 가스발생장치)에 통잔하여 착화를 시켜 쿠션이 팽창되도록 구성되어 있다.These airbags are configured to be detected as electrical signals by sensors at the time of collision and to ignite by inflation with INFLATER (gas generator of the airbag system) to expand the cushion.

상기 에어백모듈의 표면에는 커버에 의하여 폐색되어있으며 에어백 작동시 쿠션이 팽창하면서 커버에 형성된 절개부가 찢어져 쿠션이 외부로 팽창할 수 있도록 한다.The surface of the airbag module is occluded by a cover, and when the airbag is operated, the incision formed in the cover is torn while the cushion is inflated to allow the cushion to inflate to the outside.

상기와 같은 에어백모듈과 표면을 덮고있는 종래의 커버가 제 1,2 도에 도시되어 있으며 이를 상세하게 살펴보면 다음과 같다.Conventional covers covering the surface and the airbag module as described above are shown in Figures 1 and 2 and look at this in detail as follows.

커버(1)의 상측과 하측에는 주위보다 얇은 두께를 가지도록 한 상, 하측절개부두께(2, 3)을 형성하고, 상기 상, 하측의 절개부(2,3)의 중앙에서 종으로 연결된 중앙절개부(4)를 더 가지도록 되어 있다.Upper and lower incision thicknesses (2, 3) are formed on the upper and lower sides of the cover (1) to have a thickness thinner than the surroundings, and are vertically connected at the centers of the upper and lower incisions (2,3). It is intended to have a central incision 4 more.

상기 절개부(2, 3, 4)는 쿠션이 팽창할 때 찢어지면서 팽창되는 쿠션이 외부로 돌출되도록 하고 있으나, 각 절개부(2, 3, 4)와 커버(1)와의 연결부인 절개부(2, 3, 4)의 끝단부(5, 6, 7, 8)가 절개부(2, 3, 4)의 찢어짐과 동시에 찢어져 커버(1) 전체가 에어백모듈로부터 이탈되는 사례가 발생한다.The cutouts 2, 3, and 4 are torn out when the cushion is inflated so that the inflated cushion protrudes to the outside, but the cutouts that are the connection parts of the cutouts 2, 3, and 4 to the cover 1 The ends 5, 6, 7, and 8 of 2, 3, and 4 are torn at the same time as the incisions 2, 3, and 4 are torn, so that the entire cover 1 is detached from the airbag module.

이는 커버(1)의 절개부(2, 3, 4)의 두께가 일정하게 형성되어있기 때문에 쿠션팽창시 동시에 찢어지기 때문에 그 여파로 인하여 커버(1)도 동시에 찢어지는 현상이 발생하는 것이다.Since the thicknesses of the cutouts 2, 3, and 4 of the cover 1 are constantly formed, the cover 1 is also torn at the same time due to the aftermath because the sheet is torn at the same time as the cushion is expanded.

이러한 경우에는 이탈되는 커버(1)에 의하여 승차자의 안면이나 복부를 타격하여 에어백의 쿠션에 의하여 충격이 방지된 승차자에게 신체적인 손상을 가할 우려가 있는 등의 문제점을 가진다.In such a case, the cover 1 may be hit by the detached cover 1, thereby causing problems such as physical damage to the occupant whose impact is prevented by the cushion of the airbag.

이에 본 고안에서는 상기한 문제점들을 해결하기 위하여 안출이 된 것으로서 에어백모듈의 커버에 형성되는 절개부의 구조를 개선하여 커버가 함께 찢어지면서 이탈하는 사례를 방지하여 승차자의 신체적 손상을 방지할 수 있도록 한 것이 특징이다.Therefore, the present invention has been made to solve the above problems to improve the structure of the cutout formed in the cover of the airbag module to prevent the case of the cover is torn off together to prevent the physical damage of the rider It is characteristic.

이하 첨부되는 도면과 관련하여 본 고안의 구성과 작용 및 효과에 대하여 설명을 하면 다음과 같다.Hereinafter, the configuration, operation and effects of the present invention will be described with reference to the accompanying drawings.

제 3 도는 본 고안의 기술이 적용된 에어백모듈의 커버 정면도, 제 4 도는 제 2 도의 A부를 발췌한 단면도로서 함께 설명을 한다.3 is a front view of the cover of the airbag module to which the technique of the present invention is applied, and FIG. 4 is a cross-sectional view taken from the portion A of FIG.

상측과 하측에 상, 하측절개부(10,11)를 상기 상, 하측절개부(10,11)의 중앙에 세로방향으로 더 형성되는 종절개부(12)를 주위 보다 얇은 두께를 가지도록 형성하여 에어백모듈의 표면을 차폐하는 커버(15)를 구성함에 있어서; 상기 커버(15)의 상측과 하측에 형성되는 상, 하측절개부(10,11)의 중앙에 세로방향으로 형성되는 종절개부(12)의 두께(T)를 커버(15)의 상하측에 형성되는 상, 하측절개부(10,11)의 두께(T1)보다도 얇게 형성한 것이다.The upper and lower incisions 10 and 11 are formed on the upper side and the lower incision 10, which is further formed in the longitudinal direction in the center of the lower incisions 10 and 11 so as to have a thickness thinner than the surroundings. In configuring the cover 15 to shield the surface of the airbag module; On the upper and lower sides of the cover 15, the thickness T of the vertical cutouts 12 formed in the vertical direction at the centers of the upper and lower cutouts 10 and 11 formed at the upper side and the lower side of the cover 15 is formed. It is formed thinner than the thickness T1 of the upper and lower incisions 10 and 11 formed.

즉, 상, 하측절개부(10,11)의 두께(T1)는 커버(15)의 두께(T2)보다 얇고 종절개부(12)의 두께(T)는 상, 하측절개부(T1)보다 얇게 형성한 것이다.That is, the thickness T1 of the upper and lower incisions 10 and 11 is thinner than the thickness T2 of the cover 15, and the thickness T of the longitudinal incision 12 is greater than the upper and lower incisions T1. It is formed thin.

상기와 같은 본 고안은 자동차가 충돌하여 쿠션이 팽창할 때 커버(15)와 상, 하측절개부(10,11)의 두께(T1,T2)보다도 더 얇은 두께(T)를 가지도록 한 종절개부(12)가 먼저 찢어진 후 상, 하측절개부(10,11)이 찢어져 쿠션이 팽창을 도우게 된다.The present invention as described above is a longitudinal incision to have a thickness (T) thinner than the thickness (T1, T2) of the cover 15 and the upper and lower incisions (10, 11) when the car inflates the cushion. The part 12 is torn first, and then the upper and lower incisions 10 and 11 are torn, thereby helping to inflate the cushion.

그러므로, 상,하측 및 종절개부(10,11, 12)의 찢어짐한계가 상, 하측절개부(10,11)의 끝단부(16, 16', 17, 17')에서 멈추어짐으로서 커버(15)가 동시에 찢어져 이탈하는 사례를 방지할 수 있게 되는 것이다.Therefore, the tearing limits of the upper, lower and longitudinal incisions 10, 11 and 12 are stopped at the end portions 16, 16 ', 17 and 17' of the upper and lower incisions 10 and 11, respectively. 15) can be torn at the same time to prevent cases of departure.

이상과 같은 본 고안은 에어백작동시 의도하지 않은 부위가(커버)가 찢어지지 않토록 함으로서 그에 따르는 신체적 손상을 장지하여 에어백의 성능을 향상시킬 수 있는 등의 효과를 가진다.The present invention as described above has the effect that the unintentional area (cover) is not torn during operation of the airbag, thereby preventing the physical damage thereof and improving the performance of the airbag.
